adduct (UHP), a stable, inexpensive, and easily handled oxidant. The reactions were complete in 15 min at 85 °C. The melts thus obtained were reacted with excess hydrochloric acid to afford crude (dichloroiodo)arenes, ArICl2, in 64–98% yields.

Chromium(VI) oxide dissolved in a mixture of acetic acid with concentrated hydrochloric acid converts, at or near room temperature, iodoarenes to (dichloroiodo)arenes, in a very simple and efficient procedure.

Arenes (ArH) were substituted with some transient I3+ species, generated in situ in appropriate, anhydrous I2/NaIO4 or NaIO3/AcOH/Ac2O/concd H2SO4 mixtures, to form soluble organoiodine(III) intermediates, ArISO4. Next, excess concd hydrochloric acid was added to precipitate out the title ArICl2, and isolated in 46–88% optimized crude yields.

Ten representative (dichloroiodo)arenes, ArICl2, were prepared from the corresponding arenes and diiodine in variable anhydrous mixtures, ArH/I2/CrO3/AcOH/Ac2O/conc. H2SO4, followed by the addition of conc. hydrochloric acid, used as the source of chlorine; ArICl2 are useful in organic synthesis as mild and selective chlorinating and/or oxidizing agents.
